INFUENCE OF DISORDER ON THE POISSON'S RATIO OF STATIC SOLIDS IN TWO DIMENSIONS

Krzysztof W. Wojciechowski and Jakub Narojczyk

Abstract

Recent results concerning the Poisson's ratio of three simple
two-dimensional (2D) models of aperiodic structures are reviewed. The models,
which consist of mono-, bi-, and tri-atomic particles interacting through the
n-inverse-power-potential between the nearest-neighbouring atoms, were studied at
zero temperature by computer simulations. It is shown that the Poisson's ratio
increases with increasing disorder in the models.
